Description

Technical Field

[0001] This utility model relates to the field of acoustic logging pipe technology, and in particular to a multi-segment acoustic logging pipe that is easy to fix. Background Technology

[0002] Sonic logging tubes are the channels through which the probes of ultrasonic testing instruments enter the interior of cast-in-place piles during ultrasonic testing. They are an important component of the ultrasonic testing system for cast-in-place piles. In the construction of large-scale infrastructure projects such as bridges and high-rise buildings, cast-in-place piles are a critical part of the foundation structure, and their quality directly affects the safety and stability of the entire project. Defects such as segregation, mud inclusion, and pile breakage may occur during the concrete pouring process. If these defects are not detected and addressed in a timely manner, they will seriously affect the bearing capacity of the pile foundation. Sonic logging tubes, pre-embedded inside the pile, provide a channel for the probes of ultrasonic testing instruments to enter the pile. During testing, water is injected into the tubes, and the propagation characteristics of ultrasonic waves in concrete are utilized to accurately determine the integrity, strength, and presence of defects in the pile concrete, providing crucial information for project quality control.

[0003] There are various connection methods for sonic logging pipes, commonly including crimping, welding, and sleeve connection. Crimping connection uses specialized hydraulic crimpers to squeeze the double connectors at the ends of the sonic logging pipes, causing the rubber sealing rings at the joints to elastically deform, thus achieving a sealed connection between the pipes. This method is simple to operate, fast to connect, and provides good sealing performance, effectively preventing impurities such as mud from entering the pipes and affecting the detection. Welding connection involves directly welding the sonic logging pipes together using methods such as electric arc welding or gas welding. It offers high connection strength, but the welding process requires professional operation and strict quality control. Improper welding can easily lead to defects such as porosity and slag inclusions, affecting sealing and connection strength. Different connection methods have their own advantages and disadvantages. In actual engineering projects, it is necessary to select the appropriate connection method based on specific circumstances to ensure the reliability of the sonic logging pipe system and the accuracy of the detection results.

[0004] Patent document CN202543986U discloses a threaded insertion type sonic logging pipe comprising a bottom pipe, a middle pipe, and a top pipe. The bottom pipe and the top pipe are fitted into the two ends of the middle pipe. The key feature is that the bottom end of the bottom pipe is electrically welded and sealed, and the open end of the pipe body has a threaded ring. One end of the top pipe is fitted into the middle pipe and welded integrally. One end of the middle pipe is a threaded opening with a matching threaded sleeve. The top pipe and the bottom pipe are connected and sealed by the threaded sleeve. This threaded insertion type sonic logging pipe utilizes a threaded connection for the ultrasonic testing channel of the pile foundation. The threaded fixing and locking of the sealing ring effectively prevents loosening and leakage. The overall structure of the product is simple and installation is very convenient.

[0005] As in the prior art of the aforementioned patent, the sonic logging pipes are connected by threads. However, this connection method has drawbacks. Firstly, vibrations are prone to occur during cement pouring or subsequent construction, which can cause the threaded structure to loosen, resulting in lower sealing performance between the two sections of the sonic logging pipe. This can affect the subsequent ultrasonic testing and water injection process. Secondly, the pipe connection only has one sealing element. If this sealing element ages or is damaged, it will further affect the overall sealing performance of the pipe. Thirdly, due to the long length of the pipe and insufficient strength at the connection point, external forces can easily cause the pipe to bend, affecting subsequent construction and testing.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4A multi-segment acoustic logging pipe that is easy to fix includes a first pipe 1 and a second pipe 2. The first pipe 1 includes a main pipe 101 and a flared pipe 102. A fixing ring 3 is fixedly installed on the second pipe 2. The flared pipe 102 and the fixing ring 3 are connected to each other by a connecting component. A sealing component is provided between the flared pipe 102 and the fixing pipe. A reinforcing component is provided between the first pipe 1 and the second pipe 2. After the first pipe 1 and the second pipe 2 are connected, the first sealing ring 5 and the second sealing ring 11 can achieve a double seal at the connection of the two pipes, which increases the sealing performance. Secondly, the reinforcing component can increase the structural rigidity between the second pipe 2 and the first pipe 1. Multiple bolts 6 can prevent the two pipes from bending.

[0024] As a preferred technical solution of this embodiment, the sealing assembly includes a first sealing ring 5 and a second sealing ring 11. There is a groove 4 between the fixing ring 3 and the second pipe 2. The first sealing ring 5 is disposed inside the groove 4. The outer wall of the flared pipe 102 is provided with an external thread 7. The inner wall of the fixing ring 3 is threadedly connected to the external thread 7. When the flared pipe 102 is threadedly connected to the fixing ring 3 of the second pipe 2, the second sealing ring 11 can abut against the connection between the second pipe 2 and the inside of the flared pipe 102, and the first sealing ring 5 can abut against the connection between the fixing ring 3 and the flared pipe 102. The two sealing channels can increase the sealing performance of the connection between the two pipes.

[0025] As a preferred technical solution of this embodiment, the second sealing ring 11 is disposed on the inner wall of the flared pipe 102, and after the second pipe 2 is connected to the flared pipe 102, the second pipe 2 overlaps the second sealing ring 11.

[0026] As a preferred technical solution of this embodiment, the reinforcing component includes a plurality of bolts 6 fixedly installed on the fixing ring 3. The plurality of bolts 6 are arranged in a ring array with the axis of the second pipe 2 as the axis. A flange 8 is rotatably installed on the main pipe 101. The flange 8 has a plurality of flange holes 9. When the first pipe 1 and the second pipe 2 are tightened together, the bolts 6 are pre-inserted into the flange holes 9 of the flange 8, and then the flared pipe 102 and the fixing ring 3 are tightened. During the tightening process, since the flange 8 is rotatably installed on the first pipe 1, there will be no jamming, so that the bolts 6 can be inserted into each flange hole 9 on the flange 8.

[0027] As a preferred technical solution in this embodiment, the plurality of bolts 6 penetrate the flange hole 9.

[0028] As a preferred technical solution in this embodiment, one end of each of the bolts 6 is threaded with a nut 10. The nut 10 connects the flange 8 and the fixing ring 3 by connecting with the bolts 6. By tightening the bolts 6 with the nut 10, the external structure of the bolts 6, the fixing ring 3, the first pipe 1 and the second pipe 2 are further reinforced, the rigidity of the connection structure is increased, and the risk of deformation and bending of the first pipe 1 and the second pipe 2 under external force is reduced.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
